Sorry for the double post but I JUST FIXED MY ISSUE!
I was lurking on the ubisoft forum when I noticed someone has figured out how to disable the ubisoft splash screen after the loading reticle with the plane inside it, disappears.
It was here my game always seems to show a green screen, with black bars at top and bottom with only the sound from the splash screen and nothing else.
So I changed the name on the splashscreen, located /parts/core/GUI and renamed the .wmv file to a different name. When I fired up CoD it fired up on the first go, everything works great.
Hope this helps anyone else unlucky enough to come across this error.
I'll stick around on the forums though, hope to join the rest of you in the skies now.
